I had a *fantastic* tummy pillow called a Dentons pregnancy pillow (got it at spotlight) and found it wonderful, wedged under my tum (I'm a side sleeper and always have been). It was round as well as being wedge shaped and very comfy. As I got bigger I developed SPD (pelvic laxity) and needed another regular pillow between my legs - just used a thin (children's) pillow for that. Very comfy.
